We have a very big crash right now and all our coins are at a loss.
While it is very sad to have losses, a crash is also a good opportunity to sell old coins and increase / add new coins. Prices will go up again at some point and for many coins it will result in a big price increase again. Even shortly after a crash, altcoins are likely to get more profits.
It is true, that a bear market grants you the opportunity to make big profits. Now is an opportunity to bring new FIAT, if you have free FIAT available, that you can afford to lose of course, into the market because now is the chance to get big and already established tokens for a pretty nice discount. I still would not buy into ETH or Bitcoin though because they are still very expansive, but other projects might already be tempting. If you are a Fan of a project but did not invest so far because early investors already made a x100 or more with it then a bear market might be a chance to get a good entry point.
